Title: Improvements in optical measuring instruments such as inclinometers, rangefinders, heightfinders, and the like
IPC: G01C3/12
Filed: 1929-01-23
Abstract: 324,518. Barr &. Stroud, Ltd., Barr, A., and Strang, J. M. Jan. 23, 1929. Range-finders-In optical measuring instruments in which the measurement is made by the translation of a refracting prism or prisms of small angle to and fro along the path of one, or both, of the convergent beams of light, means are provided whereby the movement of the image caused by the translational movement is modified by an additional movement of an optical part, thereby modifying the scale of measurement. In one example, as shown in Fig. 2, two prisms A1 and A2 in a carrier 4 are moved in one of the two convergent beams. The rack 3 and pinion 2 give a translational motion to the prisms and the pins 5 and 6 working in slots 5<1> and 6<1> give a rotary movement. The prisms also may be situated one in each beam. In the first example the cams are not exactly similar as with prisms of finite thickness half of the image would then be displaced vertically with respect to the other half, but in the second case the two halves move together when the cams are similar. Fig. 4 shows an example using a glass plate A3 as the displacing device. The plate rotates around the axis 7 and a spring 8 holds it in contact with cam 9 placed on the shaft carrying the pinion. Fig. 5 illustrates the use of two rotating prisms A<4> and A<5> connected together by gearing and driven by a pin 11 working in the extension 10 of the rack 3. Also an objective D can be moved as in Fig. 6 by a lever 13 actuated by a cam 12 on the end of the rack 3.

Abstract: 426,228. Wireless signalling. ARMSTRONG, E. H., 211, Central Park West, New York, U.S.A. Jan. 24, 1934, No. 2436. Convention date, Jan. 24, 1933. [Class 40 (v)] Relates to means for reducing the ratio of valve " hiss " to signal strength, particularly in shortwave signalling. A wide band of frequency modulation is used, in combination with currentlimiters, and the signal is received on a circuit Fig. 2, comprising a pair of balanced detectors 56, 57, of the same general type as that described in Specification 290,642, which respond cumulatively to frequency-modulated variations and differentially to any amplitude variations. Assuming that an unmodulated carrier of 200 K.C., Fig. 5, is being received, audible valve " hiss " arising from filament variations is limited to the range from 190 to 210 K.C., and since the " reactance " characteristics of the two input circuits 52, 54 and 53, 55, Fig. 2, (represented by the curves AB and CD in Fig. 5) are equal and opposite this effect is wiped out. Hiss due to frequency variations is represented by OP-OQ, Fig. 5, plus OS-OR or PQ + SR in all, whilst signal strength is represented by OM<1>+ON<1>. On a six-metre wave it is stated that tube noise is reduced by this method to one per cent of that normally experienced. Specification 426,227 also is referred to.

Title: Method and apparatus for thermoanalytical investigations
IPC: F25D29/00
Filed: 1975-01-21
Abstract: 1484205 Temperature control METTLER INSTRUMENTE AG 21 Jan 1975 [25 June 1974] 2607/75 Heading G3R [ Also in Divisions F2 and H5] A combination of heating and cooling effects is used to control the temperature of specimens undergoing thermoanalytical investigation. The apparatus used consists of: an enclosure 16 for the specimens 22, 24, whose temperature is displayed at 48; heating means 18 for the enclosure; an adjacent (as shown, surrounding) chamber 26 for receiving cooling fluid; and means for controlling (a) the heat input to the enclosure 16 and (b) the temperature and rate of flow of the cooling fluid. The invention also includes a method of using such apparatus to vary specimen temperatures with time according to a predetermined program. In Fig. 1, the power input to the heating means 18 is controlled in dependence on the output of a temperature sensor 50. The rate of flow of cooling medium is adjusted by a valve 72 whose setting depends on the temperature at sensor 50, the temperature of the cooling medium measured by a sensor 62 and the setting of a 'desired temperature' control input 164. The inputs from 50, 62 and 164 are fed to a multi-branch bridge circuit 52 with two outputs, these outputs being fed via appropriate, including amplifying, pulse producing and PID control, units 54-58 and 64- 70 to control both the heating and cooling effects . conjointly. The circuitry of units 52, 54-58 and 64-70 is more fully depicted in Fig. 4 (not shown), which includes means for providing automatic variation of the set temperature in accordance with a desired program. The preferred cooling medium is liquid nitrogen. This is boiled in a chamber 28 from which it emerges at constant pressure, this pressure being measured at 44 and the output of an immersion heater 40 is automatically adjusted to control the rate of boiling in response to the pressure measurement. The heater 40 is depicted in detail in Fig. 3 (not shown, but see Division H5). The cooling fluid flow-rate control valve 72 vents to atmosphere at 34. The valve itself is depicted in Fig. 2 (not shown, but see Division F2). This valve is operated by a solenoid whose control is modified by a feed-back system responsive to detection of the valve element's position. Also, the temperature of the cooling medium downstream of the temperaturecontrolled chamber but upstream of the valve, is increased by a subsidiary temperature-control system 75, 77 to ensure that the valve is not 'frozen' by too-cold fluid.
